install kingbash from aur then insert following in your .bashrc
 
function kingbash.fn() {
 
  echo -n "KingBash> $READLINE_LINE" #Where "KingBash> " looks best if it resembles your PS1, at least in length.
 
  OUTPUT=`/usr/bin/kingbash "$(compgen -ab -A function)"`
 
  READLINE_POINT=`echo "$OUTPUT" | tail -n 1`
 
  READLINE_LINE=`echo "$OUTPUT" | head -n -1`
 
  echo -ne "\r\e[2K"; }
 
bind -x '"\t":kingbash.fn'
